This tool allows you to calculate the effect of the new dividend tax on an owner-managed or small family businesses. The new tax bill is calculated using the tax rates and bands for the 2016/17 tax year.

You can also view the comparable figures for the 2015/16 year (prior to the introduction of the dividend tax) to see how much the tax bill will change.

The calculator also calculates the company tax bill, and shows how much this tax bill will fall due to the planned cuts in the Corporation Tax rate between now and 2020.
